Granted: 2007-09-25
Abstract: The invention relates to a prefabricated biological purification apparatus f or the purification of domestic sewage and forms part of the technological fiel d of civil engineering. The apparatus of the invention is very versatile due t o the fact that it can be used in different types of constructions such as individual homes, condominiums, buildings, towns, etc. including a unitary facility or multiple facilities depending on requirements. The prefabricated biological purification apparatus comprises two basic units consisting of tw o containers whose size varies depending on the type and equipped with all modular elements, bottom, walls and lids, in addition to all complementary internal elements. The shape of all components makes them easy to handle, transport and assemble and no special machinery or skilled labor are required. The apparatus operates as follows: in the first unit, which is a prefabricated biological purifier, as shown in Patent Publication EP 0.878.444, that includes internal and external variations for optimized operation, the first and most important purification phase is effected, wherein the sewage is treated in three successive phases involving aerobic and anaerobic fermentation and decanting, it is possible to internally recirculate the sludges and the effluent of the purifier enters the second unit where it is evenly distributed by means of a liquid distributor. Purificatio n is completed in said unit by oxidation of contaminating matters as a result of a bacterial film that covers the filling material. A successive aerobic and partly anaerobic fermentation phase is carried out in said unit. The effluen t of the apparatus can be emptied into a receptacle involving no further treatment. As the apparatus does not produce any sludges, no regular maintenance or cleaning is required. The apparatus involves no operating costs as no machinery is needed for internal operation, and the apparatus ha s no environmental impact since the entire facility is built underground.</SDO AB>

Abstract: The conventional process for the production of a peracetic acid product, wherein hydrogen peroxide, acetic acid and water are fed into an aqueous reaction medium containing hydrogen peroxide, acetic acid, peracetic acid and an acid catalyst, wherein hydrogen peroxide and acetic acid react in the presence of the acid catalyst and form peracetic acid, and an aqueous peracetic acid concentrate is removed con- tinuously from the reaction medium by distillation, has now been improved by feed- ing the acid catalyst continuously into the reaction medium and by withdrawing continuously a portion of the reaction medium as a bottom product. When the through flow of the reaction medium is thus increased, it is purified of impurities threatening the safety of the process. If the amount of acid catalyst in the reaction medium is further decreased, a product suitable, for example, for disinfection is ob- tained from the bottom product.

Abstract: A narrow band infrared water fraction meter detects a full water cut range of a liquid hydrocarbon flow stream and a flow stream of a gas well. The water fraction meter includes a light source probe for irradiating the flow stream with a narrow band of infrared light and a light detector probe for sensing attenuation of infrared light passed through the flow stream. At a predetermined wavelength, the infrared light is substantially transmitted through gas content and liquid hydrocarbon content of the flow stream and substantially absorbed by a water content of the flow stream. Injection of corrosion/hydrate inhibiting chemicals into the flow stream can be controlled based on the attenuation of infrared light detected by the water fraction meter. For a liquid hydrocarbon flow stream, the infrared light is substantially transmitted through its liquid hydrocarbon phase and substantially absorbed by its water phase.

Abstract: Selon la présente invention, les eaux usées probématiques ayant une concentration élevée en impuretés, telles que les eaux d'infiltration d'une décharge à ordures, subissent une dégradation anaérobie dans une zone de traitement anaérobie (bassin de digestion des boues) et les boues digérées ainsi produites sont asséchées de façon mécanique. Dans le même temps, les eaux d'égouts communales sont purifiées dans une station d'épuration comprenant une zone de traitement aérobie, la réintroduction d'eau et de boues riches en oxygène et en nitrates dans la zone d'alimentation, permettant d'activer une élimination de phosphore et/ou nitrification/dénitrification précoce. Dans la zone de traitement aérobie, les boues digérées en excès dans lesquelles est incorporée une grande partie de la fraction AOX des eaux d'égouts communales, sont asséchées mécaniquement et introduites dans la zone de traitement anaérobie (bassin de digestion des boues) afin de permettre la dégradation de la fraction AOX par fermentation. Le degré d'assèchement des boues digérées en excès est régulé en fonction de la quantité d'eaux usées problématiques à traiter. Lors de l'assèchement des boues de digestion, le filtrat récupéré qui contient la plus grande partie de la fraction azotée des eaux usées problématiques, est introduite dans la zone de traitement aérobie de la station d'épuration et y est soumis à la nitrification/dénitrification.

Abstract: A boot for a universal joint is constructed by a boot body and a boot adapter. The one end of the boot is fitted on a propeller inner shaft via its one-end fitting portion and the other end of the boot is fitted on the outer race of the universal joint via its other-end fitting portion, thereby substantially covering the universal joint. The foregoing one-end fitting portion has an annular lip portion at its end portion. Passages for flowing air between the inside of the boot and the outside of the. boot are formed on the one-end fitting portion and the annular lip portion. The passages are closed by the annular lip portion being expanded in diameter outward by a centrifugal force caused by the high rotation of the propeller inner shaft, thereby preventing splashed water or muddy water from intruding into the boot when air is sucked into the boot.
